Abstract
In order to increase high power closed cycle CO2 laser performance, an experimental investigation of the velocity field in a cylindrical glow discharge tube was carried out. The axial velocity profile was measured (without electric discharge) using a laser Doppler anemometry technique at several sections of the discharge tube. The turbulent compressible flow has also been theoretically investigated by means of the PHOENICS code and comparisons of numerical results with experimental data show a reasonably good agreement.
